It's a showdown between two AFC West rivals. The Chargers will visit the Raiders tonight on Monday Night Football. Here's what to watch for:
 
1. Darren McFadden is one of the most dangerous runners in the NFL. We wouldn't be surprised if he is the game-changer.
2. Chargers look a lot different at WR: Robert Meachem and Eddie Royal are the newcomers joining Malcolm Floyd. Will they click in the new offense?
3. QB Philip Rivers vs. QB Carson Palmer: Two guys who used to be in the top tier of QBs, yet both had a forgettable 2011. Will they bounce back to elite form?
